A 20.0 mL sample of a salt solution that has a mass of 24.0 g What is the density of the solution?

density = mass/volume. (g/cm^3)
So here it is simple 24g/20ml = 1.2 g ml-1
That's it. But check your units. g cm-3 is generally used in chemistry...and luckily cm-3 = ml-1. But if your volume is in litres or weight is in kgs, just be careful with your units.
A fun side-note is that water is more or less 1g cm-3 in density. So 20ml of water = 20g. Here you have 24g, so you know 4grams of salt was added.
This IS an approximation, though. There are many subtle effects you would consider in much higher education.
-------------------------------------------------
density is in g/ml or g/cc. And, the easiest way to do these problems is to just make the units match (with something that seems logical).
You are given 20 ml & 24 g.
So you simply divide the two.
24g/20ml = 1.2 g/ml
Check your work... Does this make sense. You said it is a "salt solution" which we would expect a moderate increase in density over 1, so this seems plausible.

How can you work out the density of salt in water?
To calculate the density of salt in water, measure the mass of a given volume of the solution using a balance. Then, divide the mass of the solution by the volume of the solution to determine the density. Keep in mind that the density will vary depending on the concentration of salt in the water.
Why egg floats in concentrated salt water?
Egg floats only when the density of the salt solution is almost equal to the density of the egg.The density is made equal by making the salt solution saturaed i.e by adding more salt so that the net mass increases and thus increasing the density. Thus by displacing a small amount of water,the egg floats
What is the percentage by mass of salt solution prepared by dissolving 11 grams of salt in 80 grams of solution with solution?
The percent concentration is 13,75 %.
What is the percentage by mass of salt solution prepared by dissolving 11 grams of salt in 80 grams of solution?
13,75 % NaCl
What is the density of a salt solution compared to water?
The density of a salt solution is higher than that of water due to the additional weight of the dissolved salt particles in the water. The exact density of the salt solution will depend on the concentration of the salt in the solution.
What is the density of the salt solution if 50.0 ml has a mass of 57.0 g?
The density of the salt solution is 1.14 g/ml. This is calculated by dividing the mass (57.0 g) by the volume (50.0 ml).
What is the density in grams per milliliter of a salt solution if 210 mL has a mass of 234 g?
The density of the salt solution is calculated by dividing the mass of the solution by its volume. In this case, the density would be 234 g divided by 210 mL, which equals 1.114 g/mL.

How does dissolving salt in water change the density of the water?
The density increases as the mass of the solution increases but its volume remains the same.
What is the density of 40ml of saline solution in 50 ml beaker?
To calculate the density of the saline solution, you will need to know its mass. If the mass is not provided, you can't determine the density just based on the volume. Density is calculated as mass divided by volume.
How do you find the density of a salt solution?
Really? Density = mass/(divided by) volume congrats, you just got owned by an 8th grader =)
How does salt affect density?
When salt is dissolved in water, the mass of the water increases without a significant increase in volume, increasing the density of the solution. This is because the added salt molecules displace some of the water molecules and fill the space in between them, making the solution denser.
How do you determine the mass of salt in a solution?
To determine the mass of salt in a solution, you first need to measure the total mass of the solution. Then, you can use techniques like evaporation or filtration to separate the salt from the solution and measure the remaining mass of the solution. The difference in mass between the total solution mass and the remaining solution mass will give you the mass of the salt in the solution.
Will a boiled egg float if you add salt to water?
Yes, it will eventually. When you add salt to water, you are increasing the density of the solution, but not the volume, because the salt dissolves (dissociates). Since density is mass divided by volume, there is a direct relationship between the solution's mass and its density. They increase together even as the volume remains constant. An egg will float in a salt solultion if the molarity is about 2.5 or above.

How is the quantity of salt affected when the salt is reclaimed from a salt-and-water solution?
The mass of salt reclaimed should be the same as the mass of salt that was put into the solution.
Why does the density of water increase when salt is added to it?
Density = Mass/Volume As salt(mass) increases and the volume remains the same, density also increases.
